A fabulous king of Gaul, father of Amadis of Gaul. His encounter with the lion is one of his best exploits. It is said that he was hunting, when his horse reared and snorted at seeing a lion in the path. Perion leaped to the ground and attacked the lion, but the lion overthrew him; whereupon the king drove his sword into the belly of the beast and killed him. (Amadis de Gaul, chap. i.)
